摘要
A model equations, Time-Averaged N-S equations which is suitable for simulation of time-averaged flow in multistage turbomachines, is derived. According to engineering requirements, Time-Averaged N-S equations theory is used to simulate time-averaged flow on two levels. The first level is interface treatment technique, at this stage General Continuous Interface method is presented, following this time-average correlation terms are modeled with semi-experimental method put forward by the author, and included into computations. A two-stage fan and A one-stage fan flow-field are computed with these two method respectively. Results show that simulations are more near reality under Time-Averaged flow theory.So it is very necessary to include Time-Averaged flow simulation into turbomachinery design system, mainly Rotor/Stator interaction time-average effects must be embedded in the Time-Averaged flow simulations.
